I have a JSON object and I want to display it in the form of a table in Node.js. The table should have nested rows depending on the existence of nested records in the JSON object. I considered jstree plugin but it will be difficult to convert JSON to the JSON array needed by it. Can anyone please suggest me a better option? Any plugin or snippet that could give me a direction?
There is a third party plugin to jstree called jstree-grid:

As for converting the JSON - you can use core.data as a function and convert the format on the client side.
Try this jsonastable
Ot is a clone of json2table but MIT licensed.
You can include it in your site.

Sorry for the inappropriate question. But what do you recommend me to use to structure a library that can put a query arrangement on json formats generated by an XML parsing based on TEI p5? I tried to use GraphQL by converting the interfaces of my Angular application related to parsing information from XML to JSON in type to define a GraphQL schema but I don't think that's the way.
What I have to do is query, client only, some data encoded in XML (also wanting already parsed in JSON) and, for example, search for all occurrences of a specific data.
Do you have any roadmaps to recommend or some JSON query system that might be right for me?
You might take a look at https://www.npmjs.com/package/saxon-js. With SaxonJS you're able to run XPath expression against XML using JavaScript.
I want to pass the data in slickgrid in JSON format, How do i do that.
Please help.
You need to transform json to raw data, and pass it to instance of slickgrid. Here is API how to update grid, so use it. Also look at the Examples - one of them are using AJAX and JSON.
I am loading data from a mongodb collection to a mysql table through Kettle transformation.
First I extract them using MongodbInput and then I use json input step.
But since json input step has very low performance, I wanted to replace it with a
javacript script.
I am a beginner in Javascript and even though i tried somethings, the kettle javascript script is not recognizing any keywords.
can anyone give me sample code to convert Json data to different columns using javascript?
To solve your problem you need to see three aspects:
Reading from MongoDB
Reading from JSON
Reading from (probably) String
Reading from MongoDB Except if you changed the interface, MongoDB returns not JSON but BSON files (~binary JSON). You need to see the MongoDB documentation about reading and writing BSON: probably something like BSON.to() and BSON.from() but I don't know it by heart.
Reading from JSON Once you have your BSON in JSON format, you can read it using JSON.stringify() which returns a String.
Reading from (probably) String If you want to use the capabilities of JSON (why else would you use JSON?), you also want to use JSON.parse() which returns a JSON object.
My experience is that to send a JSON object from one step to the other, using a String is not a bad idea, i.e. at the end of a JavaScript step, you write your JSON object to a String and at the beginning of the next JavaScript step (can be further down the stream) you parse it back to JSON to work with it.
I hope this answers your question.
PS: writing JavaScript steps requires you to learn JavaScript. You don't have to be a master, but the basics are required. There is no way around it.
you could use the json input step to get the values of this json and put in common rows
Hi I am new to Java and not sure how to proceed (kindly ignore any typos or my language). Can somebody help me out (just the Idea/how to proceed, dont need any sample code). I am trying to create a Restful Json webservice (using Spring MVC).
The webservice that I am trying to create is kind of a wrapper for an existing XML based restful webservice.
The Idea is to have one common platform, since all other existing services are exposed as as JSON services.
My job is to fetch the XML transform it into a Json, but the tricky part is The Json schema is a superset of the XML schema (I mean it contains more elements that get filled with some default values).
Please let me know if you need more info.
Thanks in advance.
One way to do it would be to use Jaxb to transform the the incoming XML to Java Objects. Build your Jaxb objects in a way that it contains all the elements, the one with default values and the elements in the incoming XML.
Ones the XMl is converted into Jaxb you can use org.springframework.http.converter.json.MappingJacksonHttpMessageConverter message converter to convert your Jaxb object to Json string.
In my GWT project I need to process json data retrieved from a database via PHP. I have seen the Google examples using JavaScriptObject overlay classes. What I don't understand is why this seems to be the prefered method of processing the json data. Why shouldn't I use all native Java code to pull in the data?
Think about it the other way around: what does it mean to use POJOs? (or native Java classes as you name them)
You have to:
parse the JSON into some Java-accessible structure (e.g. com.google.gwt.json.client.JSONObject, or elemental.json.JsonObject)
create POJOs
fill the POJOs with the data from the parsed JSON structure
now you can forget the parsed JSON structure from step 1
On the other hand, with JavaScriptObject, you use JsonUtil.safeEval and TA-DA! you get your JSON parsed right into a typed Java object!
Now, to deal with JSON, there's also AutoBeans.
Choose your poison.
